Proxy ServersĪ proxy server is a server that acts as an intermediary between a client and another server (for example, a web server on the Internet). A WebSocket connection is established by upgrading from the HTTP protocol to the Web Socket protocol during the initial handshake between the client and the server, over the same underlying TCP/IP connection. The specification defines a ws:// and a wss:// scheme to indicate WebSocket and WebSocket Secure connections, respectively. To use HTML5 Web Sockets to connect from a Web client to a remote end-point, you create a new WebSocket instance and provide it with the URL that represents the end-point to which you want to connect.

Uncover emerging trends and practices from domain experts. This delivers an enormous reduction in unnecessary network traffic and latency compared to legacy polling and long-polling (Comet) solutions that are often used to push real-time data to clients or even simulate a full-duplex connection by maintaining two HTTP connections. HTML5 Web Sockets effectively provide a socket connection over the Web with minimal overhead. It introduces the WebSocket interface and defines a full-duplex communication channel that operates through a single socket over the Web. The HTML5 Web Sockets specification defines the Web Sockets API that enables web pages to use the Web Socket protocol for full-duplex communication with a remote host. Let's start with some basic concepts: what exactly are HTML5 Web Sockets and proxy servers? HTML5 Web Sockets About HTML5 Web Sockets and Proxy Servers Additionally, I’ll explain how Kaazing WebSocket Gateway and its Web Socket emulation can add additional value. Will proxy servers automatically kill WebSocket connections? Do HTML5 Web Sockets handle firewalls and proxy server issues better than Comet? Are Web Sockets the silver bullet in seamless proxy server traversal? In this article, I’ll explain how HTML5 Web Sockets interact with proxy servers, load balancing routers, and firewalls. With the recent explosion of WebSocket server implementations, a lot of questions have come up about how HTML5 Web Sockets deal with proxy servers, firewalls, and load-balancing routers.
